during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
EGFR belongs to the family of structurally and functionally similar ErbB or HER receptors on cell surfaces, which have intracellular tyrosine kinase activity. What all of these receptors have in common is that they consist of extracellular and membrane components to which ligand and intracellular components are bound via the tyrosine kinase activity . Under normal conditions the activity of Erb...
NUMBER 2 For solving general scheduling problem (including job-shop problem), order-assignment model is proposed. In this model the scheduling problem results in the selection of resource orders which are assigned for the purpose of resolving resource constraints, and the sequence of this selection constructs a search tree. The proposed algorithm for searching an optimal schedule is based on a ...
In this work we compare different methods for router workload deduction and flow classification schemes. Gigabit-routing solutions and different schemes of integrated switching and routing (Internet protocol (IP) switching) have emerged. Several flow classification schemes to be used in traffic-controled IP switching are presented and evaluated. As a new alternative, the ‘Learning Vector Quanti...
